FRAMINGHAM - State Police have identified a man and a woman from Stafford Springs, Conn. as the victims in Wednesday morning's fatal crash on the Massachusetts Turnpike.

State Trooper Todd Nolan said Thursday afternoon that 20-year-old William Barnett and 19-year-old Alyssa Grenier were killed in the 5:13 a.m. crash when the minivan in which the two were in spun out and stuck a tractor trailer carrying lumber. The crash happened on I-90 east near Rte. 9.

Barnett, who was driving the minivan, and Grenier, who was a passenger, were pronounced dead at the scene.

Nolan said that the accident is still under investigation, but said that police believe weather may have been a "large contributing factor."

The driver of the tractor trailer, a 54-year-old man from Williamsburg, was taken to the hospital with non life-threatening injuries.

The highway was closed for five hours during the investigation Wednesday morning, causing serious traffic delays during the morning rush hour. State Police said that traffic on I-90 east was backed up for 18 miles during the road closure.
